Multifractalidade e complexidade sobre commodities do agronegócio brasileiroMultifractality and complexity of the Brazilian agribusiness commodities
(Universidade Federal de Lavras, 2016)
Análise espacial de reservatórios usando DFA de dados geofísicos
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM CIÊNCIA E ENGENHARIA DE PETRÓLEO, 2014-12-17)
This research aims to set whether is possible to build spatial patterns over oil
fields using DFA (Detrended Fluctuation Analysis) of the following well logs:
sonic, density, porosity, resistivity and gamma ray. It was ...
Perceptual security of encrypted images based on wavelet scaling analysis
(Elsevier Science BV, 2016)
Turbulence characterization by studying laser beam wandering in a differential tracking motion setup
(Society of Photo-Optical Instrumentation Engineers, 2009-10-01)
The Differential Image Motion Monitor (DIMM) is a standard and widely used instrument for astronomical seeing measurements. The seeing values are estimated from the variance of the differential image motion over two equal ...
Wavelet multifractal detrended fluctuation analysis of encryption and decryption matrices
(World Scientific Publishing Company, 2013)
Wavelet-based discrimination of isolated singularities masquerading as multifractals in detrended fluctuation analyses
(Springer, 2020-04-03)
The robustness of two widespread multifractal analysis methods, one based on detrended fluctuation analysis and one on wavelet leaders, is discussed in the context of time-series containing non-uniform structures with only ...
Multifractal Detrended Fluctuation Analysis to Characterize Honey Bee Production in Semi-arid Ecosystem
(Asociación Interciencia, 2018-07)
Honey bee production could be considered as a reliable
economic indicator of the biodiversity and availability of
ecosystem services. The scaling behaviour of honey bee was
analysed and associated to the natural ecosystem ...
Temperature and precipitation in the US states: long memory, persistence, and time trend
This paper investigates the time series properties of the temperature and precipitation anomalies in the contiguous USA by using fractional differentiation. This methodology allows to capture time trend components along ...
